Optimising Geofencing - Phase 2

该项目将优化排放地理栅栏，使其比目前的系统更灵活，允许它们通过改善新巴士车队、插电式混合动力汽车和目前流通的现有车辆的排放来提高新车的性能。车辆的位置可以用来改变其行为。这项技术可用于减少特定地点的排放，例如城市中心，通常被称为地理围栏。使用土工栅栏需要车辆的准确位置、改变车辆行为的方法和定义土工栅栏运行位置的规则。目前的系统最近已被应用于公共汽车的运行，因为它们通常在市中心空气质量较差的地区运行。一些PHEV最近也引入了土工栅栏，以鼓励他们使用纯电动操作来改善空气质量。为了增加土工栅栏的使用量，从而改善整个英国的空气质量，该项目将展示更灵活的土工栅栏建筑的潜力。一方面，使定义地理栅栏的规则更加灵活-例如，允许地方当局或车队运营商根据路线拓扑、整体空气质量、交通水平或一天中的时间改变区域的范围。另一方面，通过展示如何影响私家车对地理围栏、低排放区的反应，特别是确保有效使用不断增加的插电式车辆(PHEV)的方法。最后，将使用相同的基本分析和开发方法来优化未来的移动即服务方案，同时考虑到对空气质量的直接和间接影响。这将使地方当局能够对未来推出这种综合运输模式解决方案进行规划，并对对其公民产生的更广泛影响充满信心。

This project will optimise emissions geofencing to be more flexible than current systems allowing them to enhance new vehicles performance by improving the emissions of new bus fleets, plug-in hybrid vehicles and existing vehicles in circulation today.The location of a vehicle can be used to change its behaviour. This technology can be used to reduce emissions in specific locations, for example city centres, and is often known as geofencing. The use of geofencing requires accurate location of the vehicle, a method to change the vehicle behaviour and rules to define the location where the geo-fence is operational.Current systems have been recently been applied to the operation of buses as they often operate in regions of poor air quality in city centres. Geofencing has also recently been introduced in some PHEVs to encourage their usage of electric only operation to improve air quality.To increase the uptake of geofencing and thus improve the air quality across the UK, this project will demonstrate the potential of more flexible geofencing architectures. On the one hand, making the rules that define the geofence more flexible - for example by allowing the local authority or fleet operator to vary the extent of the zone as a function of route topology, overall air quality, traffic level or time of day. And on the other hand, by demonstrating ways to influence the behaviour of private vehicles to respond to geofenced, low emission zones and in particular, ways to ensure the increasing fleet of plug in vehicles (PHEVs) are used effectively.Finally, the same underlying analysis and development approaches will be used to optimise future Mobility as a Service scenarios, considering both the direct and indirect impacts on air quality. This will enable local authorities to plan for the roll-out of such future integrated transport mode solutions with confidence in the wider impacts to their citizens.
